CCSS Description: Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor.
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
0.0/5In this worksheet, students will consider common factors of pairs of numbers, list factors of numbers, use lists of factors to identify greatest common factors, and recognize when to calculate the greatest common factor to answer word problems. Starting with common factors, in section A, students are asked to identify common factors of numbers such as 12 and 15 from a list of numbers from 1 - 9. Next, we offer learners a systematic method for finding the GCF of pairs of numbers by asking them to first list factors of these numbers. Section C consists of word problems which students will use GCF to answer.
